To (.LZZ whom, it 11mg concern:

Be it known that 1, JOHN A. SODESTROM, a citizen of the United States,residing at Sac City, in the county of Sac and State of Iowa, haveinvented a new and useful Hand-Power Brick-Machine, of which thefollowing is a specification.

' My object is to provide a machine adapted to be manually operated tomake pressed building-brick from sand and cement or other suitableconcrete material that requires no burning and that will harden andcomplete the brick as required for practical use by drying in theatmosphere.

A further object is to make parts of the machine adj ustablefor makingbrick of different width at different times.

My invention consists in the construction of elements andsubcombinations and the arrangement and combinations of all the partsrequired to produce a complete operative machine, as hereinafter setforth, pointed out in my claims, and illustrated in the accompanyingdrawings, in which Figure 1 is a side elevation of the machine and showsthe positions of the operative parts relative to each other and theframe with which they are connected, and also shows the lever inposition as required to lower the plunger in the mold to its limit foradmitting concrete to be filled into the mold. Fig. 2 is an enlargedvertical sectional view of Fig. 1 and shows the plunger in the fixedmold elevated to its limit in the mold, as required to press a brick inthe top of the mold. It also shows a modification in that the mold doesnot project above the top surface of the top of the machine. Fig. 8 is adetail view that shows an adjustable stop on the plunger for restrictingthe upward passage of the plunger in the fixed mold, as required forlifting brick out of the mold when the stop is properly adjusted.

The numeral 10 designates the frame, that is preferably made of iron andadapted to be fixed on a floor in a building or on a fixed base by meansof bolts or in any suitable way. A cross-piece 12 is fixed to the lowerportion of the frame for supporting an open-ended mold 13, that is fixedto the top of uprights 14, fixed to the cross-piece to support the moldand also serve as bearers for the slidable plunger 15, fitted in themold, as shown in Fig. 2. A cross-piece 16 at the top of the frame alsoaids in supporting the mold 13,

means of screws or in any suitable way.

At one corner of the frame there are two parallel imrights to which alever 1.7 is con nected by means of bearers a, adjust-ably fixed to theparallel uprights of the frame by means of bolts 19, extended throughbores in the uprights and slots in the bearers in such a manner that thelever can be raised and lowered relative to the fixed mold 13, as required for making brick of different widths at different times.

To connect the short arm of the lever 17 with the mold, as required toforce the plunger 15 up into the mold to compress concrete in the moldto produce a pressed brick, a metal link 18, that has a hook at eachend, is hung upon the lever and its lower end slipped over the bottom ofthe plunger, that is provided with a notch to admit the hook at thelower end of the link.

To lift the plunger 15, as required to lift the brick out of the mold, alonger link 19, provided with a hook on its end, is also con nected withthe lever 17 to engage the plunger at its lower end to transmit power tothe plunger.

To regulate the distance of the upward passage of the plunger 15 in themold, a stop 20 is adjustably connected to the face of the plunger, asshown in Fig. 8, or in any suitable way.

When brick of greater width are to be made, the lever 17 must beadjusted by lowering the adjustable bearings a on the frame 10, so theplunger 15 can be dropped lower by means of the links 18 and 19.

To pull down the plunger 15 to its limit, a detent 21 is adjustablyattached to the end portion of the hook on the lower end of the link 19.

To limit the upward-motion of the plunger at different times, the detent21 is raised or lowered on the link 19.

In Fig. 2 the mold 13 is shown to be made of wood and lined with metalplates. It is obvious it may be all metal.

A removable top 22 is placed on the top of the frame to extend outwardrelative to the frame for placing concrete thereon and receiving brickas they are pushed up out of the mold.

To close the top of the mold, a post 23 is fixed to the frame and astraight bar 24, preferably hard wood, is hinged to the lower end thatis fixed thereto in an upright position by A spring 28,fixed to the barand the top of the post, normally retains the bar elevated and out ofthe way while concrete is being filled into the mold.

It is obvious the face of the plate may be serrated 'or provided withdesigns of various forms for producing figures or ornamental faces onthe brick produced by ress ing them against the face of the plate.

In the practical operation of my machine plastic concrete is placed onthe top and the plunger lowered to its limit by raising the long arm ofthe lever, and the mold then filled with concrete and the concretescraped off evenly with the top of the mold and the bar that causes theplate to close the top of the mold lowered and locked to the frame bymeans of the latch hinged to the bar. The long arm of the lever is thenpressed down as required to complete the pressure of the concrete toform a finished brick by means of the link 18, and when the brick isthus finished in the mold and the mold-top unlocked a further depressionof the long arm of the lever will, by means of the link 19, elevate theplunger as required to push the finished brick out of the top of themold. A plate 29 is fixed on the short arm of the lever to retain thelinks 18 and 19 in place on the lever.

It is obvious the machine and mold may vary in size as required to makebrick of different length, widths, and thickness.

Having thus set forth the purpose of my invention and the constructionand function of each element and subcombination therein, the practicaloperation and utility thereof will be readily understood by personsfamiliar with the art to which it pertains.

What I claim as new, and desire to secure by Letters Patent, is

1. In a brick-machine, a frame having twouprights in parallel positionand near to each other, adjustable bearings fixed to the uprights, alever fulcrumed to said bearings, an open-ended mold fixed to the frameat the side of the lever, a plunger fitted in the mold and means foradjustably connecting the short arm of the lever with the plunger, tooperate as set forth.

2. In a brick-machine, a frame having two uprights in parallel positionand near each other, bearings provided with longitudinal slots and boltspassed through bores in the uprights and through the slots to clamp thebearings to the uprights, a lever fulcrumed to said bearings, anopen-ended mold fixed to the frame in upright position, a plunger fittedin the mold, links differing in length for connecting the short arm ofthe lever with the plunger, to operate as set forth.
